3393c90d - drm/xe/hwmon: Fix kernel version documentation for temperature

Mon, 21 Apr 2025 15:15:38 +0000

drm/xe/hwmon: Fix kernel version documentation for temperatureThe version in the sysfs attribute should correspond to the version inwhich this is enabled and visible for end users. It usually doesn'tcorrespond to the version in which the patch was developed, but rather arelease that will contain it. Update them to 6.15.Fixes: dac328dea701 ("drm/xe/hwmon: expose package and vram temperature")Reported-by: Ulisses Furquim Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4840Reviewed-by: Rodrigo Vivi Reviewed-by: Raag Jadav Link: https://lore.kernel.org/r/20250421-hwmon-doc-fix-v1-1-9f68db702249@intel.comSigned-off-by: Lucas De Marchi (cherry picked from commit 8500393a8e6c58e5e7c135133ad792fc6fd5b6f4)Signed-off-by: Lucas De Marchi List of files: /linux-6.15/Documentation/ABI/testing/sysfs-driver-intel-xe-hwmon

dac328de - drm/xe/hwmon: expose package and vram temperature

Fri, 31 Jan 2025 05:45:02 +0000

drm/xe/hwmon: expose package and vram temperatureAdd hwmon support for temp2_input and temp3_input attributes, which willexpose package and vram temperature in millidegree Celsius. With this inplace we can monitor temperature using lm-sensors tool.v2: Reuse existing channels (Badal, Karthik)Signed-off-by: Raag Jadav Reviewed-by: Andi Shyti Reviewed-by: Badal Nilawar Link: https://patchwork.freedesktop.org/patch/msgid/20250131054502.1528555-1-raag.jadav@intel.comSigned-off-by: Rodrigo Vivi List of files: /linux-6.15/Documentation/ABI/testing/sysfs-driver-intel-xe-hwmon

345dadc4 - drm/xe/hwmon: Add infra to support card power and energy attributes

Thu, 28 Mar 2024 17:54:35 +0000

drm/xe/hwmon: Add infra to support card power and energy attributesAdd infra to support card power and energy attributes through channel 0.Package attributes will be now exposed through channel 1 rather thanchannel 0 as shown below.Channel 0 i.e power1/energy1_xxx used for card andchannel 1 i.e power2/energy2_xxx used for package power,energy attributes.power1/curr1_crit and in0_input are moved to channel 1, i.e.power2/curr2_crit and in1_input as these are available for package only.This would be needed for future platforms where they might beseparate registers for package and card power and energy.Each discrete GPU supported by Xe driver, would have a directory in/sys/class/hwmon/ with multiple channels under it.Each channel would have attributes for power, energy etc.Ex: /sys/class/hwmon/hwmon2/power1_max /power1_label /energy1_input /energy1_labelAttributes will have a label to get more description of it.Labelling is as below. power1_label/energy1_label - "card", power2_label/energy2_label - "pkg".v2: Fix checkpatch errors.v3: - Update intel-xe-hwmon documentation. (Riana, Badal) - Rename hwmon card channel enum from CHANNEL_PLATFORM to CHANNEL_CARD. (Riana)v4: - Remove unrelated changes from patch. (Anshuman) - Fix typo in commit msg.v5: - Update commit message and intel-xe-hwmon documentation with "Xe" instead of xe when using it as a name.
